I only listen to female K-pop tbh, the only male K-pop idol group that can actually produce a good song is Big Bang, and if you listen to a male K-pop group for any reason besides you think its a good song, you're definately gay.
I often find that there's many songs I don't like, but the chicks in the MVs are reason enough to keep playing it over an over again. IMO the "cute innocent" type like SNSD and Kara are better than the slutty types like 2NE1. Don't look like a bunch of whores, still ****ing hot and the music is often better as well.
